OpenSLS Laser Sintering 3D Printer Made From Hacked Laser Cutter

Rice University bioengineering researchers have hacked a cheap Chinese CO2 laser cutter into a low(er)-cost laser sintering 3d printer and used it to produce fine objects such as liver structures. They claim it can be made under 10000 USD.

Materials used on it are nylon, sand, Candelilla wax, polycaprolactone (PCL) and other.

Since there is a 40-80 W of laser energy, they use custom build inter gas module to prevent burining of the material.

They have also made it open source, which deserves some gratitude from the community! Thank you Rice team! Sharing is caring!

Here is the short presentation video:

Here is the powder distribution mechanism in action:

Project has a very detailed and extensive documentation well worth reading if you are interested in laser sintering and bioprinting.
